Abstract

The image predictive encoding devicecomprises an intra frame predictive signal generation method determination sectionwhich determines, for adjacent areas comprising regenerated pixel signals and adjacent to the target area, a predictive method which is derived on the basis of data corresponding to the adjacent areas as an R mode predictive method or an L mode predictive method, an intra frame predictive signal generation sectionwhich generates an intra frame predictive signal on the basis of the R mode predictive method thus determined, and a subtractor, a transform section, a quantization section, and an entropy encoding sectionwhich encode a residual signal of a pixel signal of the target area on the basis of the generated intra frame predictive signal.
